Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The tilt angle obtaining method, device and electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, an embodiment of the present application provides a tilt angle obtaining method, which may be executed by a terminal (e.g., a control module in the terminal); but may also be performed by a stylus (e.g., a control module within the stylus); but also by other modules than the terminal and the stylus, and the embodiment includes the following steps.
S102: and acquiring the gravity data of the terminal and the touch pen.
In one example, a gravity sensor (e.g., a gyroscope, an acceleration sensor, etc.) is disposed in each of the terminal and the stylus, and the gravity data of the terminal and the gravity data of the stylus can be obtained by the gravity sensor.
In another example, the terminal and the stylus may share a gravity sensor, which may be located within the stylus. The embodiment may be executed by a terminal, and the step of acquiring the gravity data of the terminal and the stylus includes: under the condition that the touch pen is separated from the terminal, the terminal acquires (for example, acquires through a near field communication technology) gravity data of the gravity sensor as the gravity data of the touch pen; and the terminal takes the gravity data of the gravity sensor obtained before the touch pen is separated from the terminal as the gravity data of the terminal. For example, the terminal may use the gravity data of the gravity sensor collected at the last time or several times before the stylus is separated from the terminal as the gravity data of the terminal. In the embodiment, the gravity sensor and the gravity data are shared, so that the hardware cost of the terminal is saved conveniently.
Optionally, before S102, the following steps may be further included: detecting the state of the separation of the touch pen and the terminal, and executing the step S102 when the separation of the touch pen and the terminal is detected, such as the touch pen is pulled out; and under the condition that the stylus is not separated from the terminal, ending the process to save data processing overhead.
S104: and respectively establishing a space coordinate system where the terminal and the touch pen are located according to the gravity data.
The step can be that a first space coordinate system where the terminal is located is established according to the gravity data of the terminal, and the first space coordinate system can be a three-dimensional space coordinate system comprising an x axis, a y axis and a z axis; meanwhile, according to the gravity data of the touch pen, a second space coordinate system where the touch pen is located is established, wherein the second space coordinate system can be a three-dimensional space coordinate system comprising an x axis, a y axis and a z axis; the second coordinate system may also be a linear coordinate system along the axis of the stylus.
S106: and obtaining a relative inclination angle between the touch control pen and the terminal according to the space coordinate system.
As mentioned above, the spatial coordinate system established in S104 may include a first spatial coordinate system in which the terminal is located and a second spatial coordinate system in which the stylus is located, and obtaining the relative tilt angle between the stylus and the terminal according to the spatial coordinate system in this step may include: determining an included angle between the coordinate axis of the first coordinate system and the coordinate axis of the second coordinate system; and obtaining a relative inclination angle between the touch control pen and the terminal according to the included angle.
For example, in the case that the first coordinate system and the second coordinate system are both three-dimensional coordinate systems, the included angle between the x-axis of the first coordinate system and the x-axis of the second coordinate system is respectively determined; an included angle between the y-axis of the first coordinate system and the y-axis of the second coordinate system; and obtaining a relative inclination angle between the touch control pen and the terminal according to an included angle between the z axis of the first coordinate system and the z axis of the second coordinate system.
For another example, in the case where the first coordinate system is a three-dimensional coordinate system and the second coordinate system is a rectilinear coordinate system, an angle between the second coordinate system and the yoz plane of the first coordinate system is determined; and determining an included angle between the xoz planes of the second coordinate system and the first coordinate system, and obtaining a relative inclination angle between the stylus and the terminal according to the two included angles.
According to the inclination angle obtaining method provided by the embodiment of the application, the gravity data of the terminal and the touch pen are obtained, the space coordinate systems where the terminal and the touch pen are located are respectively established according to the gravity data, and the relative inclination angle between the touch pen and the terminal is obtained according to the space coordinate systems. Meanwhile, the gravity data of the touch pen and the gravity data of the terminal are fused, so that the touch pen is not in direct contact with the terminal, and the relative inclination angle of the touch pen and the terminal can be rapidly, automatically and automatically identified in a long distance.
Optionally, in embodiment 100, after obtaining the relative tilt angle between the stylus and the terminal according to the spatial coordinate system, the method further includes the following steps: identifying the holding state of the stylus by the user according to the relative inclination angle, wherein the holding state comprises left-hand holding or right-hand holding; and adjusting the interface display state of the terminal to enable the interface display state to be matched with the holding state.
It should be noted that the "adjustment" mentioned in this embodiment may be represented as a dynamic response action, and may also be represented as a static non-response action. For example, when it is recognized that the holding state of the stylus by the user is a right-hand holding, and the interface display state (e.g., a default interface display state) at this time is already an interface display state matching the right-hand holding, the "adjustment" in this embodiment may be represented as a static unresponsive; for another example, when it is recognized that the holding state of the stylus by the user is left-handed holding, and the interface display state at this time is not the interface display state matching with the left-handed holding, the "adjustment" in this embodiment may be represented as a dynamic response action, that is, a terminal interface switching action is performed once to switch the terminal interface to the interface display state matching with the left-handed holding.
As for the interface display state of the terminal, reference may be made to fig. 2 to 5, where fig. 2 shows an interface display state (or referred to as UI layout) matching with a right-hand grip, and fig. 3 shows an interface display state matching with a left-hand grip. Fig. 4 shows the interaction operation when the user holds the display screen with the right hand, and fig. 5 shows the interaction operation when the user holds the display screen with the left hand.
In the examples shown in fig. 2 to 5, when detecting that the user uses the right hand to hold, the toolbar of the interface is arranged on the same side as the user's hand, and furthermore, the interaction manner of the system UI icon or the stylus can be adapted to the corresponding right hand action. When detecting that the user holds the touch screen with the left hand, the position of the toolbar of the interface is arranged on the same side of the user, and in addition, the interaction mode of the system UI icon or the touch pen can be adapted to the corresponding left-hand action.
The aforementioned system UI icons include, but are not limited to, a toolbar, menu bar, and the like. The above mentioned interaction means: if a certain command is operated, when the right hand holds the mouse, the right slide can be triggered; if held by the left hand, left-handed sliding will trigger.
According to the embodiment, the gravity data of the touch pen and the gravity data of the terminal are fused, the left hand and the right hand can be quickly, automatically and remotely recognized to be held by the left hand and the right hand, and the interface display state and the interaction mode on the terminal (such as a mobile phone) are adjusted, so that the user experience is improved.
Optionally, before identifying a holding state of the stylus by the user according to the relative tilt angle in the above embodiment, the method further includes: detecting whether the touch pen is in an operation area of the terminal according to the gravity data; wherein the identifying the holding state of the stylus by the user according to the relative inclination angle comprises: and under the condition that the stylus is detected to be in the operation area of the terminal, identifying the holding state of the stylus by the user according to the relative inclination angle.
For example, when the touch pen is detected to move to the upper surface of the terminal (i.e., located in the operation area), the holding state of the touch pen by the user can be identified according to the relative tilt angle (e.g., relative tilt angle), so that the UI display of the terminal held by the left hand and the right hand can be adapted. For example, when the stylus is detected to move to the lower surface of the terminal (i.e., outside the operating area), the process may be terminated to trigger the anti-false touch mechanism.
The identifying the holding state of the stylus by the user according to the relative tilt angle mentioned in the foregoing embodiments may include at least one of:
1) the terminal is operated in a vertical screen mode and at 90 DEG>θ2>Δθy>θ1>In the case of 0, if 90 °>θ3>Δθx>θ4>0, recognizing that the holding state of the stylus by the user is the holding state of the right hand, and if the holding state is minus 90 degrees<-θ3<Δθx<-θ4<0, identifying that the holding state of the stylus by the user is left-handed holding;

Generally, the display interface of the terminal has a certain aspect ratio (or aspect ratio), for example, the aspect ratio is 16: 9, aspect ratio of 20: 9, etc. The vertical screen operation mentioned in relation to the above-described embodiment may be the interface display state shown in fig. 2 to 5, that is, the vertical direction of the interface display is parallel to the length direction of the terminal. The horizontal screen operation may be a display state in which the vertical screen operation is rotated by 90 degrees to the right or left, and at this time, the vertical direction of the interface display is parallel to the width direction of the terminal. The detection of the vertical screen operation and the horizontal screen operation can be realized based on a gravity sensor and a matched functional chip in the terminal.
For the spatial coordinate system shown in fig. 6, where the terminal is located, the x-axis of the spatial coordinate system is parallel to the short side of the terminal, the y-axis of the spatial coordinate system is parallel to the long side of the terminal, and the z-axis of the spatial coordinate system is perpendicular to the plane of the terminal and faces the direction of the upper surface of the terminal.
The embodiment provides an effective solution for identifying the holding state (left-handed holding or right-handed holding) of the stylus pen, and facilitates the improvement of the identification accuracy.
